OK Hood.
I think I followed most of that,getting ready for work now,will use VOM to check tonite. I know I have 24 v between gnd & 24v now so if I have 5v between gnd & dir that means they are tied together on the BOB and I could tie gnd & coms together,correct? I also understand you don't like it that way best but I have no choice if I use this BOB.
Now is where I step wayout of my league, If I understand correctly with this BOB the dir signal will vary from 0 to 5v, but you prefer a line driver (whatever THAT is) because of better noise isolation. Does that mean the dir input receives a wider voltage difference (like 5 to 24v) or just a cleaner 0 to 5v because of the isolation?
I would like to use this BOB to a least get motors jogging and verify the drives and servo motors are OK but I DON'T want to build a problematic machine susceptible to noise issues, If you think there's a better way to do things now is the time for me to change things but I would need your help to know how & what to change.
I don't personally know anyone I can talk to that would even have a clue what I'm talking about, let alone answer my questions.Thank you very much for taking your time to help me out Hood, your a gentleman and a scholar!
